The DGH supercapacitor series has 24 different value/voltage combinations, ranging in capacitance from 0.5F (Farad) to 600F with an ESR of 3mO, with working voltage (WVdc) ratings from 2.7 to 5.5WVdc. Operating temperature range of -40 ºC to 65 ºC at maximum WVdc, or from -40 ºC to 85 ºC at 2.3 volts. Multiple devices can be banked in parallel or series for even higher voltage or capacitance.
Because of the high energy storage capacity, DGH supercapacitor devices can discharge instantaneous bursts of power to smooth power interruptions, supplement batteries, or even be used in place of batteries in certain applications. Unlike batteries, the supercaps do not degrade with each cycle.
At 2.7 volts, operating life is rated at 10 years with 500,000 charge/discharge cycles. Applications for these supercapacitors include energy harvesting, IoT systems, mechanical actuators, transportation power, smart electric meters, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting and many other devices requiring maximum energy storage in a minimum of space.
There are radial, two-pin snap-in, four-pin snap-in, and dual pack configurations available, depending on voltage and capacitance combinations. Likewise, case diameters and configurations vary, depending on values. Parts are also fully RoHS compliant.
The DGH Series is available from stock at major distributors. Custom modules, with active or passive balancing, are also available, to meet higher voltage or capacitance requirements.
